Airtac MKD Multi-position Clamping Cylinder MKD20X35S
The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD20X35S is a genuine MK multi-mount cylinder (double rod), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact. As an MK unit a fixed rod stops the piston rod rotating.

About the Airtac MKD Multi-position Clamping Cylinder MKD20X35S
The MKD20X35S is a compact square-body multi-mount cylinder that fixes from 6 directions: front, back, left, right, top and bottom. Mount bodies side by side to save space, with magnetic-switch slots around the body. This double rod, double acting version has rods on both ends and a no-rotating plate that prevents rod rotation, so the 35 mm stroke keeps tooling square. Each rod side gives a theoretical 131.9 N at 0.5 MPa (the annular figure, since a rod occupies each side). Cushioning is a bumper.
You are ordering a genuine AirTAC part. MK is the no-rotating family; MD is the standard series where rotation is allowed. The trailing S means this SKU includes the magnet. We confirm dimensions and sizing from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
The 20 mm bore delivers about 131.9 N per side at 0.5 MPa; pick a larger bore if you need more thrust. MK prevents rod rotation, MD permits it. This code is a double rod unit - force on both ends - alongside double acting, single push, single pull and adjustable-stroke options. The 35 mm stroke is within the 60 mm table limit for bore 20, but the cover is short, so avoid over-long strokes. The S suffix adds the magnet; thread is PT as standard with G available. Route side-load questions to us or the datasheet.
Applications
Workpiece hold-down
Hold thin parts flat during gluing or fastening. Twin rods support the press plate at both ends and the no-rotating plate keeps it from spinning.
Label or stamp head
Drive a stamping or marking head onto parts. Rods on both sides keep the head level across the 35 mm stroke for an even impression.
Pick-and-place orienting
Extend a gripper plate into a pick station. Because the rod cannot rotate, the picked part keeps its orientation, and 6-way fixing fits crowded multi-axis frames.
FAQ
How much force does the MKD20X35S produce?
At 0.5 MPa this 20 mm bore double rod cylinder gives a theoretical 131.9 N on each rod side. Because a rod occupies both sides, the effective area matches the pull-side figure rather than the full piston figure. Operating pressure is 0.15-1.0 MPa (22-145 psi).
Where can I mount this cylinder?
The square body fixes from 6 directions: front, back, left, right, top and bottom. That lets you bolt units side by side to save space and use the magnetic-switch slots around the body. Exact body dimensions and allowable side load come from the datasheet, which we can provide.
